Yeah, thats exactly what I was thinking about it. Its a defensive mechanism, so once something is driven (or it drives) into something, that inital force is absorbed. And then the collision follows as it would have if the spring wasn't there.

The reason though why this is abvantagous particularly in the 05 is game is that it eliminates all of the minor forces that would push up on the robot. Particularly those minor ones that throw you off when you are about to cap.
